Facebook is having a promotion where you can download one of many different antivirus apps, including Panda Internet Security, Kaspersky Pure Total Security, McAfee Internet Security, and others and get 6 months free.

In order to get the deals, you'll have to "Like" the given company's Facebook page, but it's a small price to pay if you don't like our favorite, Microsoft Security Essentials, or other free options like Avast and Avira. (Note that those are also available from Facebook, but you don't get anything extra, so you're better off just downloading them from their respective sites.) You can download programs for PC, Mac, and even Android, if you feel the need for antivirus on your phone. Hit the link below to see the full list of deals.
